Square Shape Green Sapphire Watch Case for OEM Production - 3D CAD Customization with 5-8 Week Delivery
Our sapphire watch cases are manufactured using the Czochralski (CZ) method, which involves heating raw materials to melting point, then using a single crystal seed to initiate controlled crystal growth. This advanced process ensures high-quality, structurally sound sapphire crystals with excellent optical properties.
- Visible crystal growth monitoring during production
- Reduced crystal stress through free liquid surface growth
- Oriented seed crystal technology for superior crystal quality
- High mechanical strength for pressure load resistance
- Excellent thermal stability with minimal refractive index changes
- Superior chemical stability against corrosion and moisture
- High optical transmission from UV to medium infrared
- Minimal optical scattering with uniform refractive index
- Available in large window configurations
- Direct manufacturer of color sapphire boule with CZ and KY methods
- Specialized expertise in sapphire watch case production
- Custom OEM production with CAD/3D drawing support
- Precision sapphire processing and polishing
- Experienced technical team with skilled workforce
